/**
* Agent interface and event taxonomy. Every plugin programs against the
* `Agent` handle defined here; the concrete implementation lives in
* `@deepseek-ai/dsh-agent-loop`.
*
* Merge-extensible: `AgentOptions` supports declaration merging for
* plugin-specific creation options.
*
* ## Event-domain semantics (the boundary rule)
*
* The harness has three event domains, each with one job:
*
* - **`session/*`** (`@deepseek-ai/dsh-session`) — the DURABLE, replayable FACT
* log. Owns `SessionEventMap`; every entry is JSON-only (no live objects).
* One `session/event` emit per append, plus the `session/flush` parallel
* durability checkpoint. Answers "what happened, durably/replayably." A
* consumer that wants the live transcript subscribes here.
* - **`agent/*`** (this module) — the LIVE runtime surface. Always carries the
* live `Agent`. Two shapes: INTERCEPTION seams (the `agent/prompt-submit`/
* `agent/request`/`agent/session-prefix`/`agent/step-result`/
* `agent/turn-continuation` waterfalls and the serial `agent/pre-step` /
* `agent/turn-stop` checkpoints) that mutate/veto, and TRANSIENT emits
* (`agent/status`, `agent/error`, `agent/created`/
* `agent/disposed`, `agent/queued`, `agent/session-start`)
* that notify with the `Agent` in hand. Turn/step boundaries are NOT here —
* they are durable `session/event` records. Answers "right now, with the agent
* object — intercept or observe."
* - **`tools/*`** (`@deepseek-ai/dsh-tools`) — the tool registry + execution.
*
* **The rule:** a durable, replayable fact is a SessionEvent; a live
* interception or a transient/live-object signal is an `agent`/`tools` Cordis
* event. A turn/step boundary is a durable fact: it lives in the session log
* and is read off the `session/event` feed — it is NOT mirrored as an `agent/*`
* emit. A consumer that needs the `Agent` handle (or its short id) at a boundary
* keeps a session-id→agent map from `agent/created`/`agent/disposed`.
* See `docs/rfc/implemented/architecture/2026-06-11-microkernel-event-taxonomy.md`
* and `docs/rfc/implemented/simplification/2026-06-20-remove-agent-boundary-mirror-events.md`.
*
* The interception waterfalls here (`agent/prompt-submit`, `agent/request`,
* `agent/step-result`, `agent/turn-continuation`) each return a typed Decision;
* the terminal serial `agent/turn-stop` returns the stop-only subset. The
* convention is pinned by
* `docs/rfc/implemented/feature/2026-06-30-interception-seams.md`.
